Specification of Letters Patent.

Application filed.February 18, 1909. Serial No. 478,570.

To all whom it may concern: I

Be it known that I, ANKER S. LYHNE, a citizen of the United States, residing at Bridgeport, county of Fairfield, State of Conneeticufihave invented a new and useful Shade-Holdenof which the following is a specification.

' This invention has for its Qb ect to provide a simple, inexpensive and ornamental shade holder that will hold a shade firmly and securely, may be easily operated to en-' gage or disengage a shade and to engage and disengage a socket shell, which can be operated ineither direcion, shallll bf free from rb'ectin arts an in w ic -t 1e gripping it r-1311 be covered so that danger of in ury. tofthe hand of the operator shall be wholly' avoided. Y

W-iththese and other objects 1n view I have devisedthe novel shade holding device which I will now-describe referring to the accompanying drawing forming a part of this specification and using reference characters toindicate the several parts:

Figure l is an elevation of my novel shade holder as in use, a shade'being shown as gripped thereby and as attached a socket shell; Fig. 2 a partial vertical sect on on an enlarged scale showing the locking devices -inlth'e releasing position; Fig. 3 a similar. view showing the parts in the locking ppsition, the section line being indicated by in Fig. 4; Fig. 4 a sect on on the line 4.4 in; Figs. 2 and 3 lookin III the direction of the arrow, the spring c amping ring being shown in full lines in the locl' ng position and in dotted lines in the releasing position; Fig.- 5 a section on the line 5-5 in Fig' 2 looking in the direction of the arrow; and Fig. 6 is a section on the line (356 in Fig. looking in the direction of the arrow.

10 denotes a shade provided at its upper end with the usual flange ll and below the flange with a groove 12, and 13 a socket shell having near itslowcr endthe usual external rib 14.

15 denotes the body or shade securing member of my novel shade holder which may be made of any preferred ornamental configuration preferably substantially as shown in the drawing. At the lower end of the body is a vertical flange 16 which is provided with a circumferential rib 36, the inner side of which coinprises a groove 17 to receive an outwardly acting spring clamp- -fnll lines.

in rin 18. The clamping ring is provided with a plurality of outwardly extend- Patented Aug. 16, .1910.

mg bosses or bends 19, in the presentinstance three, and the flange is provided with a corresponding number of slots or openings 20 which receive the bosses or bends (see Fig. 4-).

21 denotes a locking sleeve which incloses the flange on the body, oscillates freely thereon and is retained in position by clos ing in the edges of the sleeve as zit-22 and 23 (see Figs. 2 and 3). Thesleeve is provided with a rib 24- (knurled for conven- Jence in operation), the inner side of which comprises a groove 25 to receive rib 36 on the flange and is also provided with slots or openings 96 adapted to register with slots or openings 20 in the flange.

The operation inlocking or releasing a shade will be readily understood from Figs. 2, 3 ands. The locking and releasing is effected by oscillation of the locking sleeve in either direction. flange and slots 26 in the locking sleeve are in alinement bosses or bends 19 .on the clamping ring will spring outward into said alined slots and the clamping ring will lie in groove 17 in the flange (see Fig. 2 and dotted position in Fig. 4). In this position of the clamping ring, the flange of a shade may be passed upward within flange 16 of the holder or removed therefrom. \Vhen the locking sleeve is oscillated the rear end walls of the slots in the sleeve will co-act with the front end walls of the slots in the flange (either end of said slots may be the front or rear end depending of course upon the direction of movement of the sleeve) and will engage and force the bends of the clam )ing ring inward and will move said ring rom the releasing position shown in dotted lines in Fig. 4- to the locking position shown in The clamping ring remains relatively stationary in use; that is, it has no oscillatory movement and is wholly covered in the locking position. Itis of course an open ring, the ends being left separated far enough to permit the locking movement Tn -the locking position the portions of the ring intermediate the bosses are forced under the flange of the shade and into the groove 12, thereby holder. Further forward movement of the sleeve, or bacluvaid movement thereof, will place the slots or openings in the sleeve in alinement with the slots or openings in the locking the shade firmly in the flange of the body and the resiliency of the ring Wlll cause the bosses or bends to spring outward into the alined slots, the ring moving-from the locking osition shown in full lines in Fi 4to the re easing position shown ifn dotted lines and leaving the shade wholly ree.

The locking of the holder to a socket shell is effected in a somewhat similar manner. At the upper end of body 15 is a vertical flange 27 which is provided with an internal groove 28, and with a plurality of slots or openings 29, in the present instance three.

30 denotes an outwardly acting spring locking sleeve which lies on the inner side of flange 27 and oscillates freely thereon. At the lower end of the sleeve is a flan e 31 which is turned outward to engage the ody and at the u per end is an outwardly curved roll 32 knurfed for convenience in operation. This roll engages the upper end of flange 27 and the roll and flange 31 retain the'sleeve against detachment. The sleeve is provided with a plurality of outwardly curved locking lugs or bosses 33 corresponding in number with slots or openings 29 in the flange and registering with groove 28 and the slots. The inner sides of these lu s or bosses comprise grooves 35. The 100 ing sleeve is of course a divided sleeve and 1n order to retain the ends thereof firmly in place, I preferably provide at the ends outwardly extending lugs or bosses 34: which engage groove 28 in. flange 27 in the same manner as locking In S 33.

he operation of enga ing or disengaging a socket shell is practica y the same as engaging or disengaging a shade. When locklng lu 33 are in alinement with slots 29, the resiliency of the sleeve will force the lugs outward into the slots and will ermit the sleeve to expand. In this position of the sleeve, it may be assed over the lower end of a socket shell, t 1e rib 14 thereon slipping into alinement with the groove 28 in flange 27 and the grooves 35 in the inner faces of the locking lugs. Rotation of the locking sleeve in either direction will cause the forward ends of the locking lugs (either end may b the forward end dependin on the directi 1 of movement) to engage t e inner wall ofgroove 28 in flange 27 and be forced inward thereby, the inner walls of grooves 35 in the locking lugs being forced into close enga ement with rib 14; on the socket shell and locking the holder securel thereto. Further forward movement of t e locking sleeve, or backward movement thereof, Wlll again lace the locking lugs in alinement with s ots 29 in the flange into which the locking lugs will spring through the resiliency of the sleeve thereby relieving the grip of the locking lugs on nb 14: and releasing the holder from the socket shell so that it may be readily removed. It should be noted that when the locking lugs are in the releas ng position end lugs 34 remain in engagement with groove 28, thereby holding the ends of the sleeve. securely in place. These end lugs, however, do not interfere with attachment to or detachment from a socket shell when the locking lugs are in the releasing position. Locking sleeves 21 and 30 both serve an additional purpose in that they greatly strengthen the holder and make it rlgid at the points where all the strain of use is applied.

. Having thus described my invention, I

claim:

1. A shadelholder comprising a receiving member having slots, spring means having bosses en aging. said slots and an oscillating locking 5 eeve en aging the receivingmemher and having s ots adapted to aline. with the slots in said member in the unlocking position, said sleeve when oscillated forc1 ing said spring means to the-locking position.

2. A shade holder comprising a receiving member having an internal groove and slots, spring means adapted to enter the groove in the unlocking position "and having bosses engaging the slots, and an external locking sleeve having slots adapted to receive the bosses in the unlocking position, oscillation of the sleeve acting to force said spring means to the locking position.

'3. A shade holder comprising a flange having an external rib and internal groove and slots, spring means lying in said groove and having bosses engaging the slots and a locking sleeve adapted to oscillate on the flange and having a groove which receives the rib and slots adapted to aline with the slots in the flange, said bosses being engaged and said spring means forced inward by oscillation on the locking sleeve, substantially as described, for the purpose specified.
